以某钢筋混凝土多层框架结构教学楼工程为例,采用有限元软件SAP2000,对隔震结构和非隔震结构进行模态和时程分析,并对两种结构的分析结果进行了对比,结果表明,结构布置隔震支座后,可以有效延长结构自振周期,减小层间剪力和位移。
Taking a reinforced concrete multi-story frame teaching building project as an example, finite element software SAP2000 was used to analyze the modal and time-history of isolated and non-isolated structures. The results of two kinds of structures were compared. It is indicated that the structural vibration isolation bearing can effectively prolong the natural vibration period of the structure and reduce the interlaminar shear force and displacement.
